Fix enum strict JSON validation when validators are present

[Viicos]

Change Summary

Same as #1080. While this addresses pydantic/pydantic#11070, the issue happens in many places, as reported in pydantic/pydantic#9204. The core issue is that before/wrap validators transform the input into the Python mode. This is a a though issue to address, I don't know if it's really possible to fix it properly without making breaking changes and/or tradeoffs.

Thanks!

I think the ideal solution I would like to see is for what types are accepted in each of JSON / Python logic to be decided purely based on the InputType and not at all by the physical input value. But I think this would be a large-ish refactor, so it's a future idea.
